Are you making these conclusions based on your own perceptions though, about what you think people want, or what you want, or do you have statistical evidence to back up your assertions?
I'm not claiming this to be the best FPS ever - I'm just questioning the foundation on what you are building your arguments and conclusions upon. For I suspect they are perceptions from you and maybe a few others. People here often talk from the perspective of "the players" when there is no evidence to found such conclusions.
That's all I'm saying really.
Pretty much most comments on this forum is assertions and opinions unless supported by evidence. Content creators often do surveys to assess the general opinion of players.
Maybe not from the most neutral of sources, but it is really telling that the barebones exo biology feature scores higher than the main centrepiece, FPS Combat. I assume this is because either the average player doesn't really care about fps combat in Elite (your Drew Wagars and old school players), or the average player might be interested in fps combat, but Odyssey doesn't really provide a good FPS experience. I think its a mix of both. Even the 17% that voted for FPS combat might not have voted for it because its good, just because it's best of the rest.
So by the end of this you have the space simmers that don't care for it and fps enjoyers that would've loved to have seen it done well, now not really care for it.
Its a bit like if COD Advanced Warfare, at the time, added space ships and space sim elements, but done do poorly that space simmers don't really play it. The main fps players dont really care about it because it just isn't their thing. So who is this for? The select few outliers that just don't happen to not sit in either of these categories?
Like I said, it makes no sense for Fdev to have designed this intentionally for it to be a backseat feature, therefore they must've just messed it up or just don't really know how to make a decent shooter. The lack of damage multipliers on shields, the lack of resistances, the bullet sponges, the quick shield regen to 50%, the "Lasers for shields, bullets for bodies", the constant ammo sinks, the high grind wall, the poor weapon "customisation", the 1 press of a button health packs. Its all things that you don't see in most multiplayer FPS games because it makes for very poor gameplay, and that is evident, especially with on foot PvP ...
